UPS uninterruptible power supply battery matching solution
1. After the Kehua UPS power supply received the notification that the battery can be replaced, the battery replacement implementation engineer went to the site to make preparations: ensure the input power supply of the UPS host, the registration and inspection of the new and old batteries, the sealing of the smoke detectors of the fire protection system in the computer room, Prepare carbon dioxide fire extinguishers and other related work.
 
Before replacing the battery, make relevant registration records for the Kehua UPS power supply host, old battery pack, battery monitor and other equipment, especially the placement of batteries on each layer and the wiring of the battery monitor. Mark and draw a connection diagram. . Ensure that the effect of the battery pack after replacement is consistent with the original condition.
 
2. Replace the battery of Kehua UPS power supply manufacturer, disconnect the connection switch between the Kehua UPS host and the battery pack, disconnect the Kehua UPS host and the battery pack, and ensure the safety of the staff when replacing the battery. The battery of the original battery pack is disassembled, the battery replacement implementation engineer is responsible for the battery disassembly work, and the relevant auxiliary technicians carry out the transportation of the new and old batteries.
 
When removing the old battery, place the removed battery cable and battery terminal screws neatly in a box to ensure the cleanliness and cleanliness of the computer room. After removing the old battery, place the old battery and the old battery holder neatly in the position specified by Party A. Place the new battery holder assembly at the designated position, and at the same time start to install the new battery, place the new battery on the battery holder, and adjust the placement and orientation of the new battery on the battery holder.
 
After connecting a set of Kehua UPS batteries, check whether the connecting wires of the battery terminals are firm; check whether the total voltage of the battery pack is normal, etc., and the positive and negative poles of the battery should be connected correctly.
 
3. After the Kehua uninterruptible power supply UPS battery has been replaced, use a multimeter to check the total voltage of the battery pack, the positive and negative poles of the battery pack and the wiring of the neutral wire. After ensuring that the battery pack and the UPS host are normal, turn off the switch of the battery pack to make the UPS uninterruptible power supply system work normally. Then check the working voltage, current, charging voltage, working status, etc. of the Kehua UPS power supply and make a record. One person observes whether the parameters in the LCD screen of the host are consistent with the actual ones, and the battery time parameters are debugged and set to ensure that the battery will not have false alarms during its normal life.
 
4. After the main unit of Kehua UPS power supply is debugged normally, disconnect the input power switch of the main unit of Kehua UPS, simulate the interruption of mains power failure, and test whether the UPS system can normally switch from mains power to battery backup power supply to ensure the equipment in the cabinet of the computer room. normal operation.
 
5. After the UPS battery replacement work of Kehua UPS is completed, the UPS room should be cleaned and the sundries should be cleaned to ensure a good environment of the Kehua UPS room. Restoring the preparations made in the computer room before the UPS battery replacement.
